Schedule professional HVAC maintenance twice a year for the best indoor air quality — once in the spring for cooling and once in the fall for heating. Tune-ups include cleaning the coil, replacing the filter, checking the blower, and inspecting all moving parts that contribute to the air you breathe.
Maintenance frequency
- Spring AC or heat pump tune-up
- Fall furnace or heat pump tune-up
- Filter change every 1–3 months by the homeowner
- IAQ test every 2–3 years
- Duct inspection every 5 years
The Mainstream Maintenance Plan bundles spring + fall visits, plus filter reminders, IAQ assessment, and 15% off repairs.
